A server, which is capable of communicating with a printer or printers, each performing radio frequency identification (RFID) communication with a RFID tag, contains: a record unit configured to record, in a memory device, printer identification information for identifying a printer, tag identification information for identifying a RFID tag, and communication parameters with which the printer performs RFID communication, in an associated manner; a first obtaining unit configured to obtain, from a printer, printer identification information and tag identification information read by the printer; an identifying unit configured to identify communication parameters associated with the printer identification information and the tag identification information obtained by the first obtaining unit; and a first transmission unit configured to transmit the communication parameters identified by the identifying unit, to the printer.

An arrangement and/or assembly of a set of wristbands is disclosed. In some implementations, an arrangement of a set of wristbands may include a first wristband formed from a first portion of the wristband web. The arrangement may include a second wristband formed from a second portion of the wristband web. The first length of the first wristband may be different from a second length of the second wristband. The arrangement may include a cut formation, in the wristband web, that is between the first wristband and the second wristband. The cut formation may be configured to enable the first wristband to be separated from the second wristband.

Systems and methods relate generally to a concealable marking. In an example, obtained is a printing device having a printhead, a plasma head, a platform, and a stencil holder. The printhead is configured to print to a surface of a medium. The plasma head is configured to provide a plasma. The platform is configured to support and transport the medium. The stencil holder is configured to hold a stencil between the surface of the medium and the plasma head. A region of the surface of the medium is covered with the stencil. The stencil defines at least one opening for exposure of a portion of the region of the surface. A plasma is generated with the plasma head. The portion of the surface of the medium is exposed to the plasma through the at least one opening to hydrophilize the portion of the surface thereof to provide the concealable marking.

An image forming apparatus includes a wireless tag communication device to write data to, and read data from, a wireless tag attached to a sheet. An image forming device in the apparatus is configured to form an image on the sheet. A controller in the apparatus is configured to determine whether a writing of data to a wireless tag was successful based on a notification from the wireless tag communication device and generate investigation support information if the writing was not successful and control the image forming device to form an investigation support image corresponding to the investigation support information if the writing was not successful.

A wireless tag processing device includes a wireless tag reader-writer and a processor configured to acquire first and second sets of parameter values, control the reader-writer to transmit a radio wave using each parameter value of the first set and acquire a first intensity of a response wave from a wireless tag, when a highest first intensity satisfies a first condition, determine a parameter value of the first set corresponding to the highest intensity as a parameter value to be used by the reader-writer, and when the highest intensity does not satisfy the condition, control the reader-writer to transmit a radio wave using each parameter value of the second set and acquire a second intensity, and when a highest second intensity satisfies a second condition, determine a parameter value of the second set corresponding to the highest second intensity as the parameter value to be used by the reader-writer.

A wristband configuration for receiving an accessory is described herein. In some implementations, a wristband includes a first side that includes a printable section of the wristband that includes a print coating. The wristband may include a second side, opposite the first side, that includes. The wristband may include may include a comfort coating, and an adhesive material on an adhesive section of the wristband. The wristband may include a receiving hole pattern that is configured to receive an accessory associated with the wristband and secure the accessory to the wristband when worn by a wearer.
